Abstract

Residual bone defects following cyst enucleation in the maxillofacial skeleton remain a significant clinical challenge, particularly when large osseous cavities persist as unhealed scars. Small defects may heal spontaneously, but extensive lesions compromise ridge morphology, aesthetics, and implant rehabilitation. This case report presents the management of a 36-year-old male with a persistent anterior maxillary defect five years after enucleation of a dentigerous cyst. Radiographic evaluation revealed a residual defect measuring 12.94 × 17.42 mm, unsuitable for implant placement. Reconstruction was achieved using particulate bone graft blended with platelet-rich fibrin (PRF), stabilized with a titanium mesh, and covered with a guided tissue regeneration (GTR) collagen membrane. This multimodal approach provided stability, enhanced biologic activity, and created a favorable environment for bone regeneration, enabling future implant placement. The case underscores the limitations of spontaneous healing in large cystic cavities and highlights the importance of grafting strategies combined with biologic adjuncts and barrier membranes. Such interventions transform compromised sites into rehabilitated regions, ensuring predictable functional and aesthetic outcomes.
